Overview
Henry Street Substation is an operational electrical substation in Michigan's Upper Peninsula, owned and operated by Upper Peninsula Power Company. It handles voltages of 69 kV and 12.47 kV.
Henry Street Substation is an operational electrical substation located in the Upper Peninsula of Michigan, United States. Owned and operated by Upper Peninsula Power Company, this facility serves as a critical node in the regional power distribution network, stepping down transmission-level voltage for local distribution. The substation operates at two voltage levels: 69 kV for transmission and 12.47 kV for distribution, a common configuration for substations serving mixed urban and rural loads. As part of the Upper Peninsula Power Company's infrastructure, it falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets and must comply with North American Electric Reliability Corporation (NERC) reliability standards to ensure grid stability. Located in a region with harsh winter conditions and remote communities, Henry Street Substation plays a vital role in maintaining reliable electricity supply to residential, commercial, and industrial customers. Its strategic position within the Upper Peninsula's grid helps support local economic activities and community resilience against weather-related outages.
Environmental context
The substation's location in Michigan's Upper Peninsula, a region with significant forest cover and cold winters, requires robust design to withstand snow and ice loads. The facility's voltage levels indicate it serves both transmission and distribution functions, impacting local grid stability. Proximity to natural habitats necessitates careful management of potential electromagnetic fields and oil containment from transformers to minimize ecological disruption.
